The problem is probably being caused by the variable you are assigning the
return value to. It should be a type MemHandle. You then need to lock the
MemHandle to get a MemPtr... like this..:
MemHandle vh;
MemPtr vp;
if (vh = DmNewRecord( _DBRef, _RecordPtr, _ReocrdSize )) {
if (vp = MemHandleLock(vh)) {
// USE THE "vp" POINTER HERE....
MemPtrUnlock(vp);
}
DmReleaseRecord(_DBRef, *_RecordPtr, true);
}
I'm also presuming that the _RecordPtr is pointing to something valid...?
Anyone reading this can feel free to comment on my methods 8-P
